Subject: [PATCH v2 0/3] gpio: twl4030: Correct status reporting for outputs

Hi,

As Grant commneted on the first version:
https://lkml.org/lkml/2012/12/5/53

Introduce bitfields to cache the directionand output status of the pins so we
can report them correctly.
To do this I did some cleanup within the driver to get rid of the global
variables and moved them under a private structure, changed the locking as well
to protect the bitfield operation.
As a last patch I added a note that the PWMA/B handling should not be in this
driver at all.

Regards,
Peter
